This is an inflammatory condition called lichen sclerosus. We don't know why this happens. But sometimes, I can be present and diabetics. You need to get into see a urologist for an examination and they should consider prescribing you a medication called clobetasol which is a steroid cream which can help go away. It may take 6 to 8 weeks to fully resolved. Hope this helps and let me know if you have questions.
